You can copy and paste selected rows or directly export entire resource tables to an Excel file if you prefer editing in another editor or want to send it in a generic format to your translator. When pasting back or importing Excel files also subsets are supported;
you can remove any of the language or comment columns or text rows, only the header row and the first column are mandatory.

Cut and paste are only available if you have selected a single resource file on the left - otherwise it would be ambiguous in which file to add or replace the items.
